3. INSTALLATION
3.1. Mounting Holes and Conduit Ports
The GDC-150 should be installed on a flat vertical surface with the sensor pointing
outwards in a clean, dry environment. If the GDC-150 is to be installed in a potentially
wet environment, the optional water-tight enclosure should have been selected. This
reference refers to the standard, general purpose PVC enclosure. Four mounting
holes are provided in the enclosure base for securing the GDC-150 to the wall. Do
not block the front of the enclosure as this is where the sensor is situated and where it
monitors the air for the target gas.
NOTE: Four mounting holes are provided in the enclosure base for
securing the GDC-150 to the wall. The mounting holes are 3/16
securing the GDC-150 to the wall. The mounting holes are 3/16
″ (4.8
mm) in diameter.
Conduit entry points are provided for the PVC enclosure.

The water-tight enclosure must be installed with the mounting screws passing through
the same openings that accommodate the four door securing screws. This ensures
the mounting screws are outside of the door gasket and confirms a water-tight
installation.

NOTE: No conduit entry points are provided for the water-tight
enclosure. The reason is the installer may not want one where we
would place it and this would result in unnecessary openings into this
enclosure.
